the accompanying drawings.

In the operation of explosive engines it frequently happens that the delivery of the fuel gas of the carbureter through the intake pipe or manifold is not uniform at all points of discharge, some of the heavier vapors taking one course and the others another. Where it is possible to introduce more air into the mixtures, and thereby more perfectly proportion the charge, the uniform result obtained, frequently results not only in fuel saving but in a better operation of the engine itself.

This invention relates to an air mixing 1 and fuel saving device for explosive engreatest velocity gines, that is adapted not only to insure greater uniformity in the quality of the fuel at the egress points but also obtain this result without seriously impeding or checking the intake of the fuel by the engine.

The invention consists in the matter-Shereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings,

Figure 1 is a view in perspective of a gas engine provided with an air mixer and economizer embodying features of the invention;

Fig. 2 is an enlarged view in detail of the device, as shown in connection with the manifold; partially in section and partially in elevation, and

- Fig. 3 is a view in detail of a preferred form of baflle.

As herein shown, an engine of standard type has an intake manifold 2 leading from a carburetor 3, the pipe 2 being bent as indicated and forked to provide the necessary plurality of outlets. It is quite evident that the intake suction of the engine will cause of gas on the inside corner of the elbow indicated at 4, and that frequently there will be an eddy at the opposite or larger bend of the elbow, the richer fuels, so it is found by practice, following the straightestpath possible as indicated by the dotted line 5.

Accordingly an air mixing device 6 is introduced, at this point of bond in the pipe, on

in the county of the inside angle of the elbow. A tubular easing 7 has a screwthreaded nipple, 8 insertcd in an opening through the wallof the pipe 3 at the proper angle, the passage therethrough being controlled by a tapered plug 9, held to seat by a spring 10 and manipulatedby a stem 11 and lever 12, a link 13 from the latter passing to the operators or chauffeurs station, and if desired'being provided with a suitable operating device mounted on the steering post or dash of the H vehicle.

The device'is '50 disposed that the indrawn air, when the closure 11 is in open pos1-' tion, impinges against a curved baffle plate 14:, the latter being in the form of a strip of spring material adapted for the purpose, and inserted in the outlet of the casing Where it is secured by suitable means. The degree of the are or curve which is given is dependout upon the diameter of the manifold pipe, and also .upon the local conditions where it is inserted, it being bent more or less as desired until the proper results are obtained by. adjustment- In some arrangements of the fuel intake system, it is found desirable to put the'device in the carbureter outlet, that is, in the entrance portion of the fuel intake pipe of which the carbureter outlet nipple or connection forms a part.

its a result, an air mixing and fuel econontrzing device is obtained which introduces air to the richest part of the inlet pipe, in such a manner as to evenly disseminate the indrawn air through the mixture, while the baflie, as it is set edgewise toward tli e direc tion of draft, does not impede the passage through the inlet pipe itself. As it is bendable, it can readily be adjusted to produce intake manifold of an explosive engine with an air mixer consisting of a casing adapted to be inserted in an opening in the pipe wall and provided with a' longitudinal air passage, a closure controlling the passage, and

a flat bendable baffle strip secured at the in ner end of the casing edgewise to the current through the pipe and with the concave the combination of an face in the path of the intake of air, in-

drawn through the casing.

2. The combination of an intake manifold of an explosive engine with an axially apertured casing inserted through an opening in the wall of the manifold, the passage through the casing forming communication between the air and the interior of the manifold, a closure controlling the casing passage, means for manually operating the closure and a bafile consisting of a fiat strip of bendable material curved in an arc and so CHARLES A.
